‘Mad Men’ kicks off fourth season

Press conference replaces party

The cast of “Mad Men” entered and exited the hidden third floor auditorium of the Chinese Theater on Tuesday night, before heading off to the crowded Chateau Marmont after-party celebrating the fourth season of the AMC show. Series creator Matt Weiner held court surrounded by accolytes at the chateau.

Elisabeth Moss was all business, while Vincent Kartheiser talked about his character on the show and an amiable Aaron Staton spoke of sneaking in a trip to France between gigs.

“My wife and I went to Paris and brought back a baby. She gave birth three weeks ago.”

Ten-year-old Kiernan Shipka was just as candid.

“I didn’t have to miss any school for ‘Mad Men,'” Shipka said. “We shoot my scenes in the summer.”
